Muaj nuj nqi ntawm Ribosomes . Ribosomes yog a cell qauv uas ua rau cov protein. Protein xav tau rau ntau yam cell muaj nuj nqi xws li kho kev puas tsuaj los yog coj cov txheej txheem tshuaj. Ribosomes tuaj yeem pom ntab hauv cytoplasm lossis txuas rau endoplasmic reticulum. Proteins yog ib qho tseem ceeb ntawm txhua yam hlwb.
Ib yam li ntawd, ribosomes zoo li cas hauv ib lub cell?
Ribosomes yog cov protein tsim los yog cov protein synthesizers ntawm cov cell . Endoplasmic reticulum nrog txuas cov ribosomes hu ua ntxhib ER. Nws zoo li bumpy nyob rau hauv lub microscope. Qhov txuas cov ribosomes ua cov protein uas yuav siv tau rau hauv cell thiab cov protein ua rau export tawm ntawm lub cell.
Ib yam li ntawd, ribosome yog dab tsi? Ribosomes yog ua los ntawm proteins thiab ribonucleic acid (abbreviated li RNA), yuav luag sib npaug. Nws muaj ob ntu, hu ua subunits. Lub tinier subunit yog qhov chaw mRNA khi thiab nws txiav txim siab, qhov loj dua subunit yog qhov chaw cov amino acids suav nrog.
Tsis tas li ntawd, ribosomes hauv biology yog dab tsi?
-sōm'] Ib tug kheej kheej-zoo li tus qauv nyob rau hauv lub cytoplasm ntawm ib tug cell uas yog tsim ntawm RNA thiab protein thiab yog qhov chaw ntawm protein synthesis. Ribosomes yog dawb nyob rau hauv lub cytoplasm thiab feem ntau txuas mus rau daim nyias nyias ntawm endoplasmic reticulum. Ribosomes muaj nyob rau hauv ob qho tib si eukaryotic thiab prokaryotic hlwb.
Muaj pes tsawg ribosomes nyob hauv ib lub cell?
10 lab ribosomes

Ribosomes ua dab tsi hauv lub cell prokaryotic?
Ribosomes yog cov organelles me me uas ua rau cov proteins los ntawm kev koom nrog cov amino acids ua ke. Ntau cov ribosomes pom muaj dawb hauv cytosol, thaum lwm tus yog txuas rau qhov ntxhib endoplasmic reticulum. Lub hom phiaj ntawm ribosome yog txhais cov tub txib RNA (mRNA) rau cov proteins nrog kev pab ntawm tRNA
Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Yuav ua li cas feem ntau yuav tshwm sim yog tias cov ribosomes hauv lub cell tsis ua haujlwm?
Ribosomes yog organelles uas tsim cov proteins. Cells siv cov protein los ua cov haujlwm tseem ceeb xws li kho cov cellular puas thiab coj cov txheej txheem tshuaj. Yog tias tsis muaj cov ribosomes no, cov hlwb yuav tsis tuaj yeem tsim cov protein thiab yuav tsis tuaj yeem ua haujlwm zoo
Hom cell twg muaj ribosomes thiab cell membranes?
Eukaryotes kuj tseem tuaj yeem ua ib leeg xwb. Ob leeg prokaryotic thiab eukaryotic hlwb muaj cov qauv sib xws. Tag nrho cov cell muaj plasma membrane, ribosomes, cytoplasm, thiab DNA. Lub plasma membrane, lossis cell membrane, yog txheej phospholipid uas nyob ib puag ncig ntawm tes thiab tiv thaiv nws los ntawm ib puag ncig sab nraud
Dab tsi yog cell membrane hauv prokaryotic cell?
Prokaryotes thiab eukaryotes yog ob hom cell uas muaj nyob. Tab sis, prokaryotes muaj qee cov organelles nrog rau cov cell membrane, kuj hu ua phospholipid bilayer. Cov cell membrane no kaw lub cell thiab tiv thaiv nws, tso cai rau hauv qee cov molecules raws li qhov xav tau ntawm tes
